When asked what surprised him most about humanity, the Dalai Lama answered:

Man. Because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present; the result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived.

Setting a Proper Corner Radius

Rounded corners are a key component in interface design. Apple’s iPhone, in particular, vaulted these little rounded-corner square-shaped icons into prominence. You see rounded corners everywhere these days. And all to often, I see rounded corners that seem to have been executed as an afterthought.

Designers: please spent just a few extra minutes making sure your rounded corners are done right. Examples of negligence are easiest to spot when a rounded-corner shape is inset inside another rounded-corner shape.

If the corner radius is the same for both shapes, you’ll have problems. If Square A sits inside of Square B and is smaller than Square B, the corner radius for Square A also has to be smaller. See the examples below:

Examples of proper and improper corner radii.

Its entirely possible that there’s a Mr. Wizard math formula that will help you figure out how to adjust the corner radius depending on the change in size of the shape, but I’m not smart enough to figure that out. This doesn’t have to be rocket science, though.

A designer’s keen eye is often enough to prevent the problem. Spending just a couple of extra minutes paying attention to the details will make the world a better place, don’t you think?
